Identifiers starting with an underscore and followed immediately by a capital letter are reserved by the C++ standard.
The only header guards not fixed are those in the headers auto-generated from java.
This makes the software more portable to embedded systems
and static analysis tools.
Sadly, it can't result in identical binaries because C99 mixed
declarations seem to make GCC emit superfluous stack-pointer
updates. The compiler is also somewhat dependent on the
declaration order.
